bon appareil

fonctionne bien mais le grave un peu en avant et manque un peu de définition, je vais essayé avec un dac externe.

Scott Boggs
Simple and Feature Rich

I use my s50 Pro+ to steam audio through my 1978 Kenwood 6100. I also run optical from my Samsung through the same amp, giving me volume control via the remote. Life is good.

Unfortunately the screen even at the max light its not enough visible in a sunny room . Also it did no keep the new name in BT . Otherwise its a great item

Stan Wong
S50 Pro +

The S50 pro + performs as it should and it meets all my expectation. However, the 4stream app is quite primitive and lessen the overall enjoyment. Hence the 4 stars..
